--- Comment #9 from Ralf Corsepius <rc040203@xxxxxxxxxx> ---
(In reply to Alexey I. Froloff from comment #8)
> 1. How binary can interfere with builtin?
E.g. by explictly calling them.

IIRC, some shells have settings to manipulate search orders.

Also take into account that "if" is not amongst those shell commands which
POSIX are guarantes to be built-in. I.e. your if may clash with another shell's
or other arbitrary tools external "if" at any time.

> 2. What shell have goto?
None that I am aware about, but other languages may have it and may pickup
tools from $PATH.


In any case both names, "if" and "goto" are way too common names to allow them
to be put inside in a standard path.

I'd suggest to delegate this issue to FPC and have it discussed there.

I am not familiar with osh's implementation details, but for now, I'd suggest
to install these osh-private helper programs into /usr/libexec/osh/.... and
modify osh in such a way it picks up these tools there.
